The attachment 200, specifically, the first attachment member 210 and the second attachment member 250, are coupled to each other via a magnetic force, but are not limited thereto, and various other modifications may also be made. According to another embodiment, the first attachment member 210 and the second attachment member 250 may be coupled to each other using a Velcro method.

Although not illustrated in the drawings, in the case that the first attachment member 210 and the second attachment member 250 are coupled to each other using a Velcro method, at least one hook is formed on each of the respective facing surfaces of the first attachment member 210 and the second attachment member 250 so that the first attachment member 210 and the second attachment member 250 catch and are coupled to each other.

The sizes of the hooks respectively formed on the first attachment member 210 and the second attachment member 250 may be different from each other so that the hooks may catch each other. The hooks formed on the first attachment member 210 and the second attachment member 250 may have a certain curvature of radius and may be horizontally symmetrical.

Referring to FIG. 2, the first attachment member 210 and the second attachment member 250 are respectively coupled to respective facing surfaces of the main body 100 and the plate 400, and as the first attachment member 210 and the second attachment member 250 are coupled to each other, detaching of the main body 100 from the plate 400 connected to the external ceiling C, due to gravity, and thus, dropping of the main body 100 may be prevented.

Referring to FIG. 2, the attachment 200 according to an embodiment, specifically, the first attachment member 210, may be located at a center of the surface the main body 100 (top surface in FIG. 2), and the second attachment member 250 may be located at a center of the plate 400 to correspond to a position of the first attachment member 210.

Accordingly, when a user pulls the hanger 300 that passes through the through hole 110 to be coupled to the main body 100 wherein the through hole 110 is formed in the side surface of the main body 100 that is apart by a preset distance from the center of the main body 100 where the main body 100 is coupled to the plate 400, the main body 100 may be easily decoupled from the plate 400.

The attachment 200 includes the first attachment member 210 and the second attachment member 250, and the first attachment member 210 may be coupled to the surface of the main body 100 (the top surface in FIG. 2) facing the plate 400, and the second attachment member 250 may be coupled to the surface of the plate 400 (bottom surface in FIG. 2) facing the main body 100.

Referring to FIG. 2, a user fixes the plate 400 on the external ceiling C in position to install the camera apparatus 1 in an installation area such as the external ceiling C.

Although not illustrated in the drawings, the plate 400 accommodates a certain portion of the main body 100, and as a fastening member such as a screw may pass through the plate 400 to be coupled to the external ceiling C, the plate 400 may be fixed in position on the external ceiling C.

According to the present embodiment, the attachment 200, specifically, the first attachment member 210 and the second attachment member 250, are coupled to each other via a magnetic force, and accordingly, the main body 100 where the camera 10 is installed may be fixed in position on the plate 400.

According to the present embodiment, the attachment 200, specifically, the first attachment member 210 and the second attachment member 250, are coupled to each other via a magnetic force, but are not limited thereto, and various modifications may be made. For example, they may be coupled using a Velcro method.

The attachment 200, specifically, the first attachment member 210 and the second attachment member 250, may be respectively coupled to the center of the surface of the main body 100 (top surface in FIG. 2) and the center of the surface of the plate 400 (bottom surface in FIG. 2).

Accordingly, centers of coupling areas of the main body 100 and the plate 400 may correspond to each other, and the main body 100 may be stably coupled to the plate 400, thereby preventing detachment of the main body 100 from the plate 400 and the dropping thereof.

Furthermore, the attachment 200, specifically, the first attachment member 210 and the second attachment member 250, are coupled to the center portions of the surface of the main body 100 (top surface in FIG. 2) and the center portion of the surface of the plate 400 (bottom surface in FIG. 2) to enable a user to hold the hanger 300 that is positioned outside and apart by a distance from the center portion of the main body 100 and pull the main body 100 away from the plate 400 to thereby allow the user to easily decouple the main body 100 from the plate 400.

Referring to FIGS. 2 and 4 through 8, the through hole 110 may be formed at the side surface of the main body 100, specifically, at an external side spaced apart from the center portion of the main body 100, to which the first attachment member 210 is coupled, and a certain portion of the hanger 300 passes through the through hole 110 to be positioned inside the main body 100.

Referring to FIGS. 5 through 8, in the main body 100, the protrusion 150 may protrude toward the hole 310 formed in the hanger 300. The protrusion 150 may include the protruding main body 151 and the bent portion 153.

A user may identify a position of the hanger 300 located in the main body 100 through the bottom surface hole 130 formed on the surface of the main body 100 (top surface in FIG. 5), with the naked eyes, and may have sufficient visibility to ensure that the hanger 300 is engaged with the protrusion 150, specifically, the protruding main body 151.

Referring to FIGS. 6 and 7, the protruding main body 151 protruding from the inner surface of the main body 100, toward the hole 310 formed in the hanger 300, passes through the hole 310 formed in the hanger 300, and the hanger 300 is engaged with the protruding main body 151.

Referring to FIG. 6, at the other end of the protruding main body 151 facing the one end of the protruding main body 151 coupled to the inner surface of the main body 100, the bent portion 153 that is at a certain angle with a lengthwise axis of the protruding main body 151 may be coupled.

According to the present embodiment, a lengthwise axis of the bent portion 153 and the lengthwise axis of the protruding main body 151 may be perpendicular to each other.

However, the inventive concept is not limited thereto, and other various modifications may also made. For example, the lengthwise axis of the bent portion 153 and the lengthwise axis of the protruding main body 151 may be at an acute angle with each other within the inventive scope preventing detachment of the hanger 300 from the protruding main body 151 while moving along the lengthwise axis of the protruding main body 151.

As the bent portion 153 protrudes from the protruding main body 151 toward the outside at a certain angle, the hanger 300 may be prevented from detaching from the protrusion 150, specifically, from the protruding main body 151, and the coupling force with respect to the main body 100 may be increased.

Referring to FIGS. 2 through 6, the hanger 300 may have a ring shape of a closed loop to form the hole 310 in an inner portion thereof.

Accordingly, a user may put a finger or wrist in the hole 310 formed in the hanger 300, and after decoupling the main body 100 from the plate 400, the main body 100 where the camera 10 is mounted may be prevented from being dropped and damage thereto due to the dropping may be prevented.

Furthermore, as the hole 310 is formed in the hanger 300, the hanger 300 may be engaged with the protrusion 150 protruding from the inner surface of the main body 100 even without an additional fastening member, and may be coupled to the main body 100, thereby simplifying the structure of the camera apparatus 1.

Referring to FIGS. 1, 3, and 4, as the hanger 300 is coupled to the main body 100, when decoupling the main body 100 where the camera 10 is mounted, from the plate 400 fixed to the external ceiling C, the main body 100 may be safely decoupled from the plate 400 without the need for connecting equipment such as an additional safety wire to each of the main body 100 and the plate 400.

That is, as the hanger 300 is still hung on a hand of the user, even when the user decouples the main body 100 from the plate 400, the main body 100 may be prevented from falling to the ground (lower side in FIG. 1) and being damaged.

Referring to FIGS. 1 and 2, the cover 500 is coupled to the plate 400, and as a certain area of the cover 500 corresponding to the camera 10 installed in the main body 100 is transparent, it may help the camera 10 ensure that images of the outside are obtained and prevent damage to the camera 10 due to external foreign substances.

After coupling the main body 100 where the camera 10 is mounted, with the plate 400, the user may finally couple the cover 500 with the plate 400, to thereby complete installation of the camera apparatus 1.

When regular inspection of the camera apparatus 1 or replacement of the camera 10 is required, the user may separate the cover 500 from the plate 400, and then hang the hanger 300 on the hand and pull the main body 100 away from the plate 400, to thereby decouple the main body 100 where the camera 10 is mounted, from the plate 400.

Referring to FIG. 3, the hanger 300 may be formed of a flexible material such as fabric, silicon, or rubber.

Accordingly, the user may fold the hanger 300 and store the hanger 300 inside the plate 400 without removing the hanger 300 from the main body 100.

In the camera apparatus 1, the protrusion 150 protruding in the main body 100, specifically, the protruding main body 151, passes through the hole 310 formed in the hanger 300 such that the hanger 300 is engaged with the main body 100.

Accordingly, compared to a camera apparatus according to the related art where a main body, in which a camera is mounted, and a plate are coupled to each other by using a pin method, an additional fastening structure is included, and where two hands are needed to decouple the fastening structure, according to the camera apparatus 1 according to the present embodiment, a user may use one hand by putting a finger in the hole 310 formed in the hanger 300 and pulling the main body 100, where the camera 10 is mounted, away from the plate 400 to remove the same, thus improving convenience in terms of installation and replacement.

In addition, according to the camera apparatus of the related art using the pin method, when removing the main body where the camera is installed, from the plate, there is no component connecting a user to the main body, and thus, there is a high risk of dropping the main body where the camera is mounted. However, according to the camera apparatus 1 according to the present embodiment, as the camera 10 is coupled to the main body 100, with which the hanger 300 that is put in the hand of the user is stably engaged, the fall of the camera 10 may be prevented.

Referring to FIG. 2, the hanger 300 passes through the through hole 110 formed outside and apart from the center portion of the main body 100 to be engaged with the protrusion 150, specifically, the protruding main body 151, and protrudes out of the main body 100, and thus, the user may constantly visibly recognize the presence of the hanger 300.

Accordingly, when removing the main body 100 where the camera 10 is mounted, from the plate 400, to replace the camera 10, gripping important components of the camera 10 such as a lens may be prevented, thereby significantly reducing the probability of malfunction of the camera 10.

Referring to FIG. 3, as the hanger 300 is formed of a flexible material such as fabric, silicon, or rubber, after coupling the main body 100 to the plate 400, the user may fold the hanger 300 and store the same in a space formed inside the plate 400, thereby improving the efficient use of space and ensuring easy storage.

Hereinafter, the structure, operating principle, and effect of a photographing system according to an embodiment will be described. Referring to FIGS. 1 through 8, the photographing system according to an embodiment may include the camera apparatus 1 and the plate 400. The camera apparatus 1 is where a camera is installed and may include the main body 100, the attachment 200, and the hanger 300.

The plate 400 is fixed to the external ceiling C in position and may be coupled to the camera apparatus 1. Details of the structure, operating principle, and effect of the camera apparatus 1 including the main body 100, the attachment 200, and the hanger 300, and the plate 400 are described above, and thus, repeated detailed description thereof will be omitted.

According to the camera apparatus according to the present embodiment, configured as described above, when pulling the hanger, the main body may be easily decoupled from the plate by a relatively small force, and thus, convenience in terms of installation and replacement may be improved.

In addition, as the hanger is provided, an additional component such as a safety wire, for preventing detachment of the main body from the plate, is not required, thereby simplifying the structure of the camera apparatus.

In addition, as the hanger is provided, the possibility of gripping important components of the camera such as a lens or the like around the hanger may be reduced, thereby preventing malfunction of the camera.
